  1. 1. Modelling Micropollutant Removal Through Ozonation in Wastewater

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Maximiliano Andrés Oportus Foster; [2023]
    Nyckelord :Micropollutants; water reuse; wastewater treatment models; ozonation; computer modeling; water and environmental engineering; Technology and Engineering;

    Sammanfattning : Proper management of water resources is a key to climate change adaptation and resilience in modern societies. Adequate treatment of wastewater is essential for ensuring the sustainability of the water cycle and the health of the environment and the ecosystems that inhabit it. LÄS MER

  3. 2. Artificiella torskrev i Hanöbukten: Förstudie

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Tobias Krätzer; [2023]
    Nyckelord :Artificiella torskrev; Hanö; torskpopulation; Östersjön; övergödning; överfiske; Earth and Environmental Sciences;

    Sammanfattning : Torskpopulationen i Östersjön påverkas negativt av övergödning och överfiske. Man vill därav främja torskpopulationen omkring Hanö genom att placera ut artificiella rev. LÄS MER

  4. 3. Wastewater Characterisation for Design and Modelling of Primary Settlers at Municipal Wastewater Treatment Plants

    Master-uppsats, Lunds universitet/Industriell elektroteknik och automation

    Författare :Louise Westin; [2023]
    Nyckelord :Primary Settling Tank; Wastewater Treatment; Settleometer; Particle Settling Velocity Distribution; Modelling.; Technology and Engineering;

    Sammanfattning : The primary settling tank (PST) is often one of the first treatment steps at a wastewater treatment plant (WWTP) and is the first process in the plant to remove significant amounts of suspended solids. Its role in wastewater treatment however, has oftentimes been neglected and little effort has been made to optimize and model the process. LÄS MER

  5. 4. Faktorer som påverkar blekning av cellulosa : En dataanalys vid bioraffinaderiet Domsjö Fabriker AB

    Master-uppsats, Umeå universitet/Institutionen för matematik och matematisk statistik

    Författare :Joe Lindehag; [2023]
    Nyckelord :pulp; biorefinery; statistics; data analysis; Cellulosa; bioraffinaderi; statistik; dataanalys;

    Sammanfattning : Domsjö Fabriker AB har under en tid haft en stigande vattenförbrukning utan att kunna peka på någon bidragande faktor. Som ett led i denna utredning har en dataanalys över blekeriet med fokus på variabeln Chemical Oxygen Demand (COD) genomförts. LÄS MER

  7. 5. Finding ways of optimizing coagulant dosage, for a more sustainable wastewater treatment process

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Hanna Sjöman; [2023]
    Nyckelord :Wastewater treatment process; coagulant dosage; COD; machine learning; water and environmental engineering; Technology and Engineering;

    Sammanfattning : The wastewater treatment process at Oatly consists of several treatment steps of which, two are chemical treatment steps involving coagulation followed by flotation to remove phosphorous and COD. The coagulant dosage is mainly determined based on the operator’s experience and supported using results from jar tests. LÄS MER
